To wHoM ITMAY CONCERN.:

Be it known that I, JOHN B. VAN HO'RN, .of Trenton,.in Mercer county,and State of New Jersey, have invented new and useful Improvements inClamps to beUsed `in Bending Carriage-Bows, Felloes, and other purposes;and I hereby declare the following to be a full and exact descriptionofthe same, reference being had to the drawings that accompany and formapart of these specifications.

The object of'my invention is to provide a clamp to'be used in bendingbows, felloes, springs, and like'pur- 7 poses,` that can be operatedmuch quicker than any now in use.

Figure 1, perspective view, showing my clamp with section ofa bow asheld by my` device. Figure, -2, sectional or side lview, on line a. b,showing the different parts.

Letter A, clamp, with flange e on each inner side. These flanges vare,cut at an angle on the underside,

forming a wedge-like surface, as shown in fig. 2. K

Letter B, wedge, being'straight on the side coming against the 'wood orarticle to be held, and the other being an inclined plane, operatingagainst the iiauge e, as shown in the drawings. This wedge B isconstructed with a recessed top, which furnishes a'. convenienthand-hold, and by means of which the wedge can readily be inserted andwithdrawn when the clamp is used for ordinary purposes, without theassistance of a hammer "or any other tool. i

v Letter D represents the ends of carriage-beweer other article to beheld.

These clamps may be made of metal or wood, as may seem desirable, and inaccordance with the work they are to be appliedto. For carriage-bows',felices, Snc., they may be made fast to the frame yor set, and crowdingthe wedge in-by the hand will oftentimes be all that is required, or ablow from a hammer or mullet will drivethe wedge home.

It w'illbe readily seen that for the above-described purposes my deviceis more easily and quickly adjusted l .than those provided with bolt andscrew. v

What I claim, and desire to secure by Letters Patent, is- The clamp A,having angular flanges e e,`in combination with the'wedge B, when. thesame is constructed as described, and the whole operated substantiallyas described and for the purpose specified.

In testimony whereof, I have signed my name to this specification in'thepresence of two subscribing witnesses.

vJOHN B. VAN HORN.
